    Study Notes

    Defects in Solids

    • The equilibrium concentration of vacancies in a material at a specific temperature is called the thermodynamic equilibrium concentration of vacancies.

    Types of Defects

    • One type of defect that is NOT a type of defect in a solid is a perfect crystal.

    Crystallographic Directions in HCP Crystals

    • The correct notation to represent crystallographic directions in HCP crystals is Indices notation.

    Crystallographic Planes in Cubic Crystals

    • The correct notation to represent crystallographic planes in cubic crystals is Miller Indices notation.

    Types of Crystal Lattices

    • The most common type of crystal lattice is the Face-Centered Cubic (FCC) lattice.
